Why the sky is BLUE?


During the day, Rayleigh scattering, a phenomenon, gives the sky its blue appearance. Sunlight strikes air molecules like oxygen and nitrogen when it enters the atmosphere of the planet. Blue light, which has shorter wavelengths than other colors, is scattered more than other colors by these gas molecules in all directions.  This causes the blue light to be more widely dispersed and visible from all angles, giving the appearance that the sky is blue. As the sun is lower in the sky at sunrise and sunset, more of the Earth's atmosphere must be traversed by the light, which scatters even more of the shorter blue wavelengths and causes the sky to seem more red, orange, or yellow.

Cool Facts & Stats

Lightning is a giant discharge of electricity accompanied by a brilliant flash of light and a loud crack of thunder.

It is freaking HOT and POWERFUL!....

  • The spark can reach over five miles (eight kilometers) in length, 
  • It can raise the temperature of the air by as much as 50,000 degrees Fahrenheit (27,700 degrees Celsius)
  • It contains approximately 100 million electrical volts.

Some interesting statistics

  •  Lightning detection systems in the United States monitor an average of 25 million strokes of lightning from clouds to ground during some 100,000 thunderstorms every year.
  • It is estimated that Earth as a whole is struck by an average of more than a hundred lightning bolts every second.
  • The odds of becoming a lightning victim in the U.S. in any one year is 1 in 700,000. The odds of being struck in your lifetime is 1 in 3,000.
  • Lightning can kill people (3,696 deaths were recorded in the U.S. between 1959 and 2003) or cause cardiac arrest.
  • Injuries range from severe burns and permanent brain damage to memory loss and personality change.
  • About 400 people survive lightning strokes in the U.S. each year.

  • People should stay away from windows and doors and avoid contact with anything that conducts electricity, including landline telephones. Most people hurt by lightning while inside their homes are talking on the telephone at the time.
  •  People shouldn't be swimming during the thunderstorm; it is very dangerous because water is a good conductor of electricity
  • An umbrella can increase your chances of being struck by lightning if it makes you the tallest object in the area.

What is Acid Rain?

Obviously, it is not manmade chemical solution....
  • Acid rain is rain, snow, sleet, or hail that contains acids. Acid rain harms lakes and rivers and kills fish and other water life.Scientists believe it damages forests, soil, statues, bridges, and buildings too. 

  • When chemicals from automobiles and factories mix with the water, they form acids. Most of those chemicals come from burning coal, oil, and fuel. Acid rain has caused damage in parts of North America, Europe, and Asia. Since the 1950's, the damage is worse. Now it harms areas far away from cities.
